S TEM WINDING AND SETTl NG WATCH.

SPECIFICATION forming part of Reissued LettersPti-tent No. 11,323, dated April 11, 1893. Original No. 472,987, dated April 19, 1892. Application for reissue filed February 13, 1893. Serial No. 462,209.

To all whom it may concern:

Be it known that I, EDWIN H. FIJINT, of Cincinnati, in the county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Stem Winding and Setting Watches, for which Letters Patent of the United States No. 472,887 were issued upon the 19th day of April, 1892, whichLetters Patout have been found to be inoperative and [O invalid and not to cover the invention set forth in the specificatiomand shown in the drawings which were filed in the Patent Office upon the 11th day of May, 1891, preparatory to the obtaining of the said Letters Patr 5 cut. Now therefore, being desirous of reissuing' the said Letters Patent, I have prepared and do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the accompazo nying drawings, in which Figure 1 is a plan'view, from the front side, of a watch containing my improvements, the dial being removed and the parts shown in position for winding the main spring. Fig.

2 is alike view of the same with the parts in position for setting the hands, a portion of the intermediate wheel being removed to show the plate beneath. Figs. 3 and 4, are plan views of said watch from the rear, with the 0 back plate removed, and-the stem or pendant in longitudinal section, and show, respectively, the arrangement of parts when the winding and the setting engagements are efiected. Fig. 5. is a like view of the same, the fulllines showing the relative positions of parts when vthe stem arbor has been retracted to shift the engagement from winding to setting, and the dotted lines the positions of the same after such engagement has been effected. Fig. 6, is a plan view of the swinging bearing for the intermediate wheel, and the back ratchet mechanism employedin connection therewith, the full lines showing the normal positions of the ratchet device,'and the dotted lines the positions of the same when said intermediate wheel is about to trip over a'tooth of the winding wheel. Figs. 7 and 8 are perspective views from opposite sides, of the parts composing the setting and winding mechanism, separated from each other, and Figs. 9 and 10 are sections upon lines cc, a, of Figs. 3 and '5, and

\ show, respectively, the positions of parts when in winding engagement andafter the stem arbor has been retracted for changing such engagement.

Letters of like name and kind refer to like parts in each of the figures. V

The design of my invention is to enable the winding and hands setting engagements'or' a watch movement to be controlled entirely by the movements of a stem arbor which has no positive connection with the movement, and

to such end my said invention consists, in 'a stem winding and setting-watch in which the winding and setting engagements are effected by the movements of the stem arbor, substantially as and for the purpose hereinafter specified. In illustrating my invention, such parts, only, as are necessary for an understanding 7o of its construction and operation, will be shown and described, among which is a casecenter A, that is provided with the usual pendant or stem a, and has within such pendant, a stem arbor B which is provided upon 7 5 its outer'end with an ordinary crown b, and has its inner, squared end I) projecting, into the movement space, and is adapted to be rotated and to be moved longitndinallywithin said pendant. .So

Fitted into and secured Within the case center A, is an ordinary front movement plate 0, which at one edge is provided with a nearly circular notch c that receives and contains a correspondingly shaped plate 0 which is securedin place thereon by screws 0- and-0 Upon the inner face of said plate 0, in aline with the stem arbor B, is a cannon pinion D that is journaled within a suitable bearing 0 is provided with a square anial opening which receives and contains the squared end b of said arbor, and has such diameter of its toothed portion as to cause the same to project through an opening in said plate, a sufficient distance to enable its teeth to engage 5 with the teeth of a wheel E located upon the outer face of thesame. The wheelE isjournaled upon avhubfthat is formed upon and projects from one side of aplate F, which has the form of a disk. Said plate is pivoted at or near one edge to or upon the inner face of the plate 0, at a point opposite to and in a line axially with the cannon pinion D, while its said hub projects forward through a suitableopening c a distance sufficient to enable it to receive and journal said wheel E. A pin G, having" upon its outer end a fiat head g, passes inward through said wheel E and hub f, and at its inner end is provided with a transverse opening g, which receives a piu 9 that operates to confine said part-stogether, while permitting said wheel to rotate freely, and said plate to turn with equal freedom upon its pivotal, eccentric'allylocat ed bearing.

Pivoted upon the movement plate (3, at one side of the plate Ois a wheel H, which is in engagement with or forms part .of a winding train, while upon the opposite side of said plate 0, is pivoted a secondwheell that has engagement with a hands setting wheel, which said wheels are so arranged as'to enable the wheel E, by themovements of the pivoted plate F, to be swung into engagement with either, without disengagement from the pinion D. The slight friction of the wheel E upon its bearing, is sufiicient to cause the pivoted plate F to turn upon its bearing, and to move said wheel into engagement with the wheel H when the stem arbor is rotated in one direction, and to movethe sameinto engagementwith the wheel I when said arbor is rotated inan opposite direction. In-Yorder that when thus engaged said wheelE maybe prevented from being moved out of engagement by thereverse rotation of said stem arbor, there is secured upon the hub f, a block K which is provided with a tongue it that projects radially toward the stem arbor, and has such length as to enable it to pass by the inner end of the same.

when the latter is drawn to the outer limit of its longitudinal motion, while when said pivoted plate is turned to the limit of its motion in either direction, and said stem arbor is pushed longitudinally inward, said tongue engages with the projecting inner end b of the latter, whenever the same is turned in an opposite direction, and thus operates as a stop .orlock.

From'the foregoing, it will be seen that to change the engagement of the stem arbor from winding to setting, it is only necessary to pull said arbor outward, partially rotate it in the necessary direction, and then move said arbor to the inner limit of its longitudinal motion.

When the stem driven train is in winding engagement, it is desirable, that the teeth of the wheels, E and II, should be able to move apart when the stem arbor is rotated backward, so as to produce What is commonly known as a? back-ratchet action. This result is effected by pivoting the block Kupon the hub f, and securing upon the plate F, the tail piece Z of a curved spring L, which spring has its said tail piece located at one side of said block, and its free end in engagement with the opposite side of the same. As the point of contact between the free end of said spring and said block is between the. pivotal bearing of the latter, and its tongue it, it operates to hold said block with a yielding pressure against said tail piece Z, in its normal position, from which the winding of the watch has no tendency to move said block,

' but when said stem arbor is turned backward,

said spring will yield sufficiently to enable the teeth of the wheels E and H to slip over each other, as described. In setting the hands, the teeth of the wheels E and I have no tendency to separate when the stem arbor is rotated in one direction, while when said arbor is rotated in an opposite direction, the block K is rigidly held, and no separation is practicable.

In the foregoing description, my invention is illustrated as applied to old watches,but 111 applying su'ch invention to new watches,,tl1e mechanism will .be attached directly to the frontmovement-plate,insteadof through the medium of the plate C and the corresponding notch in said movement plate.
